Casting method for beam guard plate of gyratory crusher

Abstract

The invention discloses a casting mold and casting method for a beam guard plate of a rotary type crusher and belongs to the technical field of casting. The casting mold comprises internal sand cores and an external sand mould, and a cavity is formed between the sand cores and the sand mould. The sand mould (cores) is (are) positively arranged in accordance with the pouring position of the beam guard plate, and the sand mould of the beam guard plate is divided into three sand mould monomers, namely L1, L2 and L3, from top to bottom. The sand mould monomer L1 is arranged in an upper case, the sand mould monomer L2 is arranged in a middle case, the sand mould monomer L3 is arranged in a lower case, the three sand mould monomers are arranged in an overlapping mode, and the sand cores are not layered. The beam guard plate is positively casted, and a three-case molding casting process is adopted, so that the problem that high-position risers are fed to low-position risers is solved, and the waste of molten steel is reduced; and the number of the risers is reduced, the appearance destruction of castings is reduced, the residue time of artificial riser grinding is shortened, labor cost is saved, the production cycle is shortened, and the appearance quality of the beam guard plate castings is guaranteed.

Description

technical field [0001] The invention relates to the technical field of casting, and more specifically, relates to a casting method of a gyratory crusher beam guard plate. Background technique [0002] In metallurgy, construction, chemical building materials, mining, refractory materials and other industries, it is necessary to crush and pulverize ores with high hardness such as magnesia and high-alumina bauxite. Smooth edges and corners, no flaky particles, good appearance. The gyratory crusher is a large-scale crushing machine that uses the gyratory motion of the crushing cone in the cone cavity in the shell to squeeze, split and bend the material, and roughly crush ores or rocks with various hardnesses. Therefore, it is widely used in metallurgy, construction, Widely used in mining and other fields. [0003] The beam guard is an important part of the gyratory crusher and is made by casting. Such as figure 1 As shown, it is a beam guard plate of a gyratory crusher, whic...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to overcome the problems existing in the existing casting process of the beam guard plate of the gyratory crusher: 1) there are many risers remaining, which affects the appearance quality of the beam guard plate casting, and manual polishing is time-consuming and laborious; Riser feeding leads to the waste of molten steel. A casting mold and casting method for the beam guard plate of the gyratory crusher is provided; The problem of feeding to the low-level riser reduces the waste of molten steel, and the number of risers is reduced, the appearance damage of castings is reduced, and the residual time of artificially polished risers is shortened, which saves labor costs and shortens the production cycle. Appearance quality is also guaranteed
